Title:
xserver-xorg crash, probably synaptics
Status in xorg package in Ubuntu:
Invalid
Bug description:
Ubuntu 14.04 LTS with xserver-xorg-lts-utopic and linux-generic-lts-
utopic installed to even make touchpad work. The system can run for
days without any problems, but sooner or later a spontaneous segfault
will happen and return to the login screen.

Xorg's log also gets filled up with these messages
http://codepad.org/dLKc2JJo which makes me suspect Synaptics is to blame for
the eventual segfault:
(EE) BUG: triggered 'if (priv->num_active_touches > priv->num_slots)'
(EE) BUG: ../../src/synaptics.c:2991 in UpdateTouchState()
